Salary Info for a Construction Worker. According to the U.S. Bureau of Labor Statistics (BLS), the average hourly wage of a construction worker was $16.84 in 2013 (www.bls.gov).Typically, construction workers who are employed by nonresidential building companies earn a higher salary than workers on residential building and utility systems projects.he BLS predicted a 25% job growth for construction careers from 2012-2022. With population increases and the need for improvement of roads, buildings and bridges, construction workers who are willing to relocate and have specialized training may have the best job opportunities.
@Huck Smith ...err then that is not a histogram. A histogram is a crude estimate of the probability density function of a univariate (in the conventional sense of a histogram) variable. Hence, in a histogram the x-axis represents the single variable and the y-axis is the estimate of the density of the data at values on the scale of x. The information about plot(), write(), and read.csv() were very useful to me. The terminology related to plot and histogram is something I can use.
The y axis is scaled so that the total area of the histogram bars is 1. In detail, the probability density histogram is created by: Dividing the data into intervals â see Number of Bins in a Histogram. Counting the number of data points in each interval. Dividing the counts by the total number of data points. Dividing that result by the interval width as shown on the x axis, to obtain the height of the bar along the y axis. In a probability density histogram, the larger the numbers on the x axis, the smaller the numbers on the y axis must be to keep the total area at 1. In a relative frequency histogram, the height of each bar represents the proportion of the data (the fraction of all the iterations) in that bar.
